APPARATUS FOR STORING AND DISPENSING HYDROGARBON LIQUIDS.

Specification of Letters Patent.

Application filed October 2, 1907. Serial No. 395,498.

Patented March 23, 1909.

To all whom it may concern:

Be it known that I, JOSEPH B. EVANS, a citizen pf the United States, anda resident of Selma, in the county of Dallas and State of Alabama, haveinvented a new and Improved Apparatus for Storing and DispensingHydrocarbon Liquids, of which the following is a full, clear, and exactdescription.

This invention is an improved apparatus for storing and dispensinghydrocarbon and such volatile liquids as gasolene.

The invention embodies in its construction a tank which is at all timeskept in a filled condition, whereby evaporation of the liquid issubstantially prevented and the danger of explosion practicallyeliminated.

The apparatus is constructed for the use of retailers,'garages, etc.,more especially where a water pressure suppl is not obtainable or maynot be convenient y had.

Reference is to be had to the accompanying drawing forming a part ofthis specification and w erein is represented the preferred embodimentof my improved apparatus partly in central vertical section.

The apparatus essentially-consists of two tanks 1 and 2 with means forforcing the liquid contained in the tank 1, into the tank 2, anddscharging it back thereinto, together with means for discharging the hdrocarbon liquid from the tank 2 as it is displaced by the other liquid.The tank 1, should be of slightly greater capacity than the tank 2 inorder that the contents thereof when in a filled condition will be morethan sufficient to expel the hydrocarbon liquid in the tank mounted uponand rigid with the tank 1, am is provided with a suitable discharge pipe3 having a controlling-valve 4 and connected with the tank through theintermediary of a valve-casing 5, the latter containing a valvecomprising a valve-head 6 attached to the upper end of a stem 7 which isslidable in and maintained in a substantially vertical position by suitable guides 8, as shown. One of these guides 8, it will be observed, isin the nature of a spider which is clamped in place between thescrew-threaded sections of the casing 5.

Between the. guides of the valve-stein 7 there is attached thereto afloat 9 of such specific gravity as to sink with the yalve in gasoleneor other like liquid but buo antly V0 in such iqi iilds 1e mcans'empoyed for forcing the liquid of valves 12 being provided at theoppositesidesof the pump for causing the flow of the water in thisdirection.

The bottom of the tank 2 is provided with a discharge in the nature of apipe 13 leading to a point near the bottom of the tank 1 and having acontrolling-valve 14 which is accessible at the outside of the tank. Thetank 1 is further provided with a vent pi e 15 vertically rising fromits top. The l dwer portion of the tank 2 is provided at the exteriorwith a gage 16 in the form of the usual transparent tube, and the .to ofthe tank carries a filling plug or pipe 17 having a controllingvalve 18,the said pipe being threaded at its outer end for receiving a hosecoupling of the hose employed in refilling the tank.

Assuming the tank 1 to be filled with water and also the lower portionof the tank 2 to the point indicated, which may be observed through thega e 16, and the upper portion of the tank 2 filed with a hydrocarbonliquid, suchas gasolene, when it is desired to draw a quantity ofgasolene, a measure or other receptacle is placed under the dependingend of the discharge pipe 3 and the valve 4 opened. 'By now operatingthe pum 10, the water from the bottom tank 1 will e forced into the tank2, causing such quantity of the gasolene as desired to be dispelled,thus keeping the tank 2 in a filled condition. When substantially all ofthe gasolene has been drawn from the tank 2 and the water level hasassed to the float 9, the valve will be forci ly seated, therebypreventing the water from passing through the discharge ipe. To againrefil the tank 2 with the hydi'ocarbon liquid, the valve 4 is closed anda hose leading from the barrel in which the said liquid is contained isapplied to the pipe 17. On now opening the valves 18 and 14 the waterflows back to the tank 1 and the suction caused thereby drawslthegasolene into the tank 2. When the water has again sunk to its originallevel, the

valves 14 and 18 are closed and the apparatus is again in readiness fordispensing purposes. It will be necessary at times to add to the waterin order to maintain its level passed thereto, and a pipe leading, fromthe slightly above the top of the tank 1, whereby it may not be possiblefor the gasoleneto ass into this tank; this being accomplished byintroducing the water through the vent p1pe. 17. V T The invention asshown and described while being my preferred ractlcal embodiment of thesame is nevert elesssusceptible to modifications within the scope of'theappended claims. c

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

returning the water thereto.

ottom of the second tank to a oint closely adjacent to the bottom of therst tank for 2. The combinationof atank adapted to contain water, asecond tank superposed thereon adapted to contain a hydrocarbon liquid,a manually-operated pump connected with the lower portion of thefirst-named tank and discharging into said second tank, a valve-casingconnecting with the upper ortion of the second tank, a'discharge p1peeading from the valve casing, a float-controlled valve contained withinsaid casing for automatically cutting off the discharge through saidpipe when the Water level has passed thereto, a pipe leading from thebottom of the second tank to a oint closely adjacent to the bottom of.the rst tank for returning the water thereto, a vent rovided at the topof the first-named tan and a water age connected with the second tank atthe ower portion thereof;

- 3. The combination of two tanks arranged at different elevations, thehigher tank a'da ted to'contain a hydrocarbon -li uid and the oWer tankadapted to contain a iquid of higher specific gravity, a dischargeleading from the upper portion of the up er tank, a pump for passing theliquid of big er specific gravity from the lower portion of the lowertank to the lower portion of the upper tank, and means for returning theliquid of higher specific gravity from the upper tank to the lower tank,by gravity.

4. The combination of two tanks arranged at different elevations, thehigher tank adapted to contain a liquid of one specific gravity, and thelower tank adapted to contain a liquid of a higher specific gravity, adischarge leading fromthe upper portion of the upper tank, means forforcibly introducing the liquid of higher specific gravity from thelower tank into the upper tank, and means for returning the hquid ofhigher specific gravity from the upper tank to the lower tank bygravity.

In testimony whereof I have signed my name to this specification in thepresence of two v subscribing witnesses.
